OIL-CAN PUMP.

SPECIFICATION forming part of Letters Patent No. 283,834, dated August 28, 1883.

Application filed March 3, 1883. (No model.)

To all whom it may concern.-

. Be it known that I, EDWARD MUG. TURNER, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Oil-Gan Pump, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to pumps for oil-tanks of that class which are used for dispensing kerosene and other oils; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in-the claim.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved oil-can pump. Fig. 2 is a vertical sectional view, showing the pump in position for operation in an oilcan, parts of the pump-cylinders having been broken away for the purpose of better illustrating the construction. Fig. 3 is a horizontal sectional view on the line 1; o in Fig. 2. Fig. 4 is a vertical sectional view on the line as x in Fig. 3. Fig. 5 is a vertical sectional view on the line 1 y in Fig. 3, and Fig. 6 is a horizontal sectional view on the line 2 z in Fig.2.

The same letters refer to the same parts in all the figures.

A in the drawings refers to the oil-tank in which my improved pump is fitted. This tank is herein shown for the purpose of illustrating the arrangement and operation of my improved pump; but it is not herein claimed, as it will be made the subject of a separate appli cation for Letters Patent.

B is the main pump-cylinder, which is provided at its lower end with a seat, 0, for aball valve, D, above which is a cross-bar, E, to prevent the displacement of the said valve. The upper end of cylinder B has a screw. cap or cover, F, serving to hold in position an elastic packing disk or washer, G.

II is the piston or plunger which works in the cylinder B. The piston is mounted upon a stem or rod, 1, which extends upwardly through a perforation in the cap and washer, and is provided with a suitable handle, J.

K is a cylinder, secured adjoining the cylinder B, with which'it is connected by an opening, L, at its lower end. The bottom of the cylinder K is closed. Above the opening LT it is provided with a seat, M, for a ball-valve, N, which is prevented from displacement by a cross-bar, 0, arranged abovef P is a supplementary cylinder, arranged adjoining the cylinders B and K, and connected with the former by an opening, Q, near its upper end. The cylinder P is provided near its iywer end, which is open, with a seat, R, for a all-valve, S, above which a crossbar, T, is

arranged to prevent displacement. In the upper end of the cylinder 1, above the opening Q, is a seat, U, for anotherball-valve, V, which is likewise held in place by a cross-bar, WV. It is not absolutely essential that the several valves herein described should be ball-valves. Other valves of any suitable construction opening upward may be used with equally successful results; but I prefer ball-valves, as being more simple and less liable to get out of .order than other differently-constructed valves. The upper ends of the cylinders K andl? open into the discharge-pipe X, the upper end of which terminates in a bottle-spout, Y, having a ridge, Z, to prevent it from fitting too tightly in the mouths of bottles and jugs that are to be filled, thus allowing the air to escape as the fluid passes in. The pipe X passes through and is firmly secured in a circular plate or disk, A provided near its edge with a downwardly-projecting pipe, B forming a flange, the lower end of which is connected by abrace, G, with the lower end of the discharge-pipe, as shown.

The tray D of the oil-tankAis provided with an opening, E of sufficient size to admit the cylinders forming the pump and the pipe or flange B The edge of the disk A rests upon the upper edge of ascrew-threaded collar F surrounding the opening E, and is held in place by a screw-cap, G. Suitable packing may be interposedin order to makea tight joint.

H is a tapering or conical brace secured on the under side of the tray surrounding the opening E The lower end of this brace fits tightly against the flange or pipe B thereby holding the pump steady during operation.

The operation of my improved pump will be readily understood from the foregoing de- 100 scription, taken in connection with the drawings heretoannexed. On the upstroke of the piston or plunger the lower end of the cylinder B is filled through the valve D, and fluid is discharged from its upper end through the opening Q and valve V. On the downstroke of the piston fluid enters the cylinder P through the valve S, and passes from thence through theopening Q into the upper end of the cylinder B. At the same time fluid passes from the lower end of the latter through the opening Linto the cylinder K, up through the valve N in the latter, and to the dischargepipe.

This pump, it will be seen, is double-acting, and will raise and throw a continuous stream of fluid. By simply dispensing with the supplementary cylinder P, a single-acting pump may be produced, which, being simpler and less expensive, may in some cases be found preferable.

I claim as my invention and desireto secure by Letters Patent of the United States In an oil-can pump, the combination of the cylinders, constructed and arranged substantially as described, the discharge-pipe, the

disk or plate secured upon the latter,'and provided near its edge with a downwardly-pro- EDWARD MOGAUGHEY TURNER.
